A marvelous, humane, comprehensive look at the mysteries of chronic fatigue syndrome. Dr. Bell, perhaps the best medical writer I have ever encountered, takes on an immensely complex subject and sets forth in clear and concise terms what is known about CFS, what still isn't, what theories and treatments have been rejected and what theories and treatments are still under exploration, and where he thinks the future is headed. Most importantly, Dr. Bell clearly and decisively rejects the misguided notions that this disease is somehow the product of malingering or just a fancy word for depression, and offers encouragment to those who suffer not only from the disease but from the frustration of not being understood by their families or their physicians. I cannot recommend it highly enough for anyone with an interest in CFS.
